Live Electron Holography: Window to the Phase World

While the idea of electron holography has been around for over 50 years, the technology necessary to establish a window to the phase world is only now becoming available. This is the first report of an all digital system for displaying the image phase continuously and live, instead of looking at one frame at a time after initiation of the reconstruction procedure. The technical requirements, including the necessary image processing steps which differ from the standard reconstruction procedure for single frame holograms, will be discussed, and current time demands for image acquisition and the different elements of image processing will be laid out. The modified requirements for continuous, live processing will be discussed in detail, and images obtained in the live mode will be shown.
